“Mark Tuna creates unique specialty glass architectural features that are truly one-of-a-kind statements. His beautiful glass designs make such a remarkable difference in a space. Mark has been designing and creating beautiful windows, doors and other architectural features, in coordination with interior designers and architects for over thirty-five years. A designer can come to Mark with an idea, and Mark will elevate it to a whole new level.”

Paige & Michael Doumani

“In 1992, my husband and I bought our dream home in lower Bel Air. We spent one and a half years remodeling and one of our challenges was finding someone who could not only repair our original diamond-shaped lead glass windows, but also make new ones with the same severe undulation, for the addition. There were plenty of people who offered to make the windows sections flat, but Mark was the only one who gave us the confidence that he could indeed duplicate the difficult design so that all of our windows matched. Not only did he do what he said he could do, but he did it in precisely the time promised.

The quality of his work was unparalleled and our experience with him was one of pure pleasure. Mark is an artist, through and through and his passion for his God-given gift is something that made our journey with him, memorable. He is trustworthy and a true professional.

My husband and I couldn’t be more enthusiastic about his work or about him personally. We highly recommend his services.”

Butch Flint

“I have been a client of Mark’s for over fifteen years. Together we have worked on intricate and complex leaded glass designs. Mark is a super decent guy. He has great expertise, skill, reliability, patience, and creative taste. Mark and his studio Glass Visions, is my first choice for excellent craftsmanship in glass design and construction. Working with Mark is always an enjoyable experience.”

Thomas Landry Designs

“Mark is one of few European artisans continuing the centuries old tradition of stained glass working. His passion for the organic life that is captured in an unusual colored or textured glass is matched only by his inexhaustible knowledge of how to use glass not only technically but in such a beautifully artistic way. So many times I have gone to Mark with only a concept and a dream and he has created the most incredible and timeless art to be enjoyed by myself and clients for decades to come.”

“Mark Tuna is the proprietor of the aptly named, Glass Visions Studio – because Mark truly is a visionary! When my wife and I were looking for a signature piece for our home, Mark was kind enough to give us a tour of his studio, patiently explained his artistic process and then took our ideas and made them beautifully realized! His work and craftsmanship is unparalleled and simply gorgeous. Not only do we love the results of his work, we proudly recommend him. Mark is a kind, generous artist who puts his heart and soul into his work. If you have the chance to add stained glass to your home or office, Glass Visions Studio is the only place to go!”

Sheila Balkin

“Mark Tuna, owner of Glass Visions made over 40 stained glass windows for my house on the Venice Canals. The windows are magnificent and magical. Mark incorporated pieces of antique European glass in select places to give a combination of an Old World and contemporary look. He is a visionary artist with a remarkable talent for capturing the feeling of a project. My house with its spectacular glass windows was featured in the Los Angeles Times and on the cover of Fine Home Building Magazine. People passing by regularly stop to take pictures, and some have asked if they can take their wedding photos in front of the house. I recommend Mark Tuna and Glass Visions for any project, large or small, where stained glass is an option.”

Scott Murray

“I was very fortunate that the Italian woman who designed my kitchen knew of Glass Vision Studios. I wanted to have a custom stained glass dome installed in the foyer of my residence along with stained glass covers for the sky lights, leaded glass windows and even some transoms. Mr. Mark Tuna is without a doubt the BEST person to handle any custom stained glass work you might ever have the need to have constructed. His eye for detail and many years of experience makes his work similar to that you see in historical churches in Europe and the like. I would definitely use Mark for any and all of my stained glass and or leaded glass work and not hesitate to recommend him to anybody needing his discipline of work.”
